We report on the recent brightening of the AGN candidate MASTER OTJ013135.43+555831.5. On November 13th,2016 MJD(2457705.82), The source had NIR fluxes corresponding to J = 15.163 +/- 0.04, H = 13.679 +/- 0.05 AND Ks = 12.497 +/- 0.05. While, on MJD 2457687.9 the flux in the H band corresponded to H = 14.547 +/- 0.06. Hence, the source doubled its flux in this rather short lapse. This fact and the observed NIR colors render support to the idea that it is an AGN. Spectroscopic data is highly desirable. Our observations are carried out with the 2.1m telescope of the Guillermo Haro Observatory operated by the National Institute for Astrophysics, Optics and Electronics (Mexico), equipped with the instrument CANICA a NIR camera. We encourage further multi wavelength coverage.
